기초의 지지방식 중 깊은 기초로 분류되는 말뚝기초는 일반적으로 고강도의 기성강관(Spiral Steel Pipe)을 재료로 한 말뚝을 사용하는 것이 설계 및 시공측면에서 유리하나, 현재 국내 외의 치솟는 건설원자재 비용 및 고유가에 따른 장거리 운반비용의 증가와 더불어 건설현장에서의 경제적 부담이 상당부분 증가되고 있는 실정이다. 특히, 개발후진국을 비롯한 건설 산업의 국제적 진출에 대한 활기와 더불어 해외현장 변동상황(원자재의 수급 문제에 따른 공기지연 및 경제성) 등을 고려하면 이에 대한 능동적인 대처가 절실할 수 있다. 본 사례는 중동지역 $\bigcirc\bigcirc$조선소의 이러한 현장여건을 고려하여 중 소하중 규모의 크레인 기초에 적용된 말뚝의 구조 해석적 검토와 지역 지반조건을 반영하여 안정하고 현지조달이 가능한 말뚝 재료의 변경을 제안한 경우이다. 본 검토에서는 기초 말뚝의 정역학적 허용지지력과 기초지반 조건을 고려한 항타관입 분석 및 크레인 이동하중을 고려한 응력해석을 실시하여 최대연직력, 모멘트, 전단력, 응력비 등을 비교하였으며, 동일한 검토조건하에서 결과를 바탕으로 변경 가능한 말뚝을 선정하였다. 기초지반에 대한 적정안전율을 갖는 허용지지력 및 구조적 안정성의 확보가 가능한 콘크리트 말뚝으로의 변경이 가능하며 상부하중 규모에 따라 설치간격에 따른 파일본수의 증 감이 발생되었다.

The Sea road which is connected from the Gulf of Persia to Canton was completed by Arabs in the end of the eighth century. For the first time in history, the amount of goods by the sea route exceeds land route. In contrast with the Mediterranean, the Indian Ocean was a sea of peace. Its western shores were under Muslim control, thus we find in this age a great expansion of commerce on the Indian Ocean. We trace the sea route to China in use in the middle of the ninth century. Also we find out that the outstanding feature of the medieval Arab ship of Indian Ocean are two: the manner in which planks of the hull sewn together, not nailed; and the fore-and-aft set of the sails.

울창한 숲에도 어느 정도 햇빛은 들 듯이, 태양복사에너지는 식생의 잎과 흙에 모두 미치며, 그로 인해 증산과 증발이 각각 발생한다. 이러한 사실을 반영하는 것은 현존하는 증발산 산정 방법을 개선하여 더 나은 증발산 추정치를 구하는 데에 도움이 될 것이다. 이 연구에서는 증발 표면을 수직적으로 흙층(soil layer)과 잎층(canopy layer)으로 나눠진 다층 구조로 바라보고, 각 층에서 증발산을 계산하는 방법을 도입했다. 증발 표면을 수직 상에서 구분했기에 각 층의 환경 조건은 그 층을 대표하는 높이에서 관측된 기상자료를 활용할 수 있다. 또한, 식생 활기에 따른 각 층의 복사에너지 유입량과 기공의 여닫힘에 따른 Bowen 비를 통해 식생이 증발산에 미치는 영향을 반영하는 것이 가능하다. 본 연구에서는 Fluxnet에서 제공하는 공분산 방법(eddy covariance method)으로 측정한 자료를 참고하여 다층 구조가 실제 증발산 산정에 타당한가를 논했다. 시스템 내 변화는 주어진 조건에서 엔트로피가 최대로 생성되는 방향으로 발생한다는 Maximum Entropy Production (MEP) 이론을 기반으로 만들어진 증발산 산정법을 통해 각 층의 증발산을 계산했으며, 관측 증발산을 토대로 잎층과 흙층에 유입된 복사에너지의 크기를 비교했다. 결과적으로 잎층에 계산된 복사에너지 흡수능이 낙엽수림의 변화 주기를 잘 반영하는 것을 확인했으며 다층 구조를 도입하는 것이 증발산 산정 향상과 수문-식생 관계를 고려한 증발산 분석에 적절한 접근법임을 보였다.

Oriental Medicine Shopping District in Kyungdong Market developed through moving the Jongro which has been the center of oriental medicine since Joseon dynasty period. This shopping district grows up as a wholesale center based on convenient traffics. In 1994, herb clinics are major industry. But in 2007 the number of herb clinics has been reduced, while drug stores have increased. And doctors' age becomes older. Oriental Medicine Shopping District in Kyungdong Market occupies the center-stage of medicinal stuff's distribution and approximately 70% of the stuff come from other parts of the country. The district seems to be developing and modernizing comparing to the past. But it is not true. In this paper, I explain this phenomenon as "inertia about place". Oriental Medicine Shopping District in Kyungdong Market is suffering, but it tries to raise itself as the biggest oriental medicine market and new tourist site for they are designated as Hanbang Special District.

The purpose of this following research is to verify influence of brand personality development of domestic Internet shopping malls on consumer satisfaction and intention to revisit. To achieve this purpose, a sample study was carried out on college students in Busan who made a purchase from Internet shopping malls during the past 6 months. In the concrete, 11 shopping malls including general shopping malls and open market that have a high market share were chosen as comparison targets. Materials were collected and analyzed through questionnaire survey. Empirical analysis results are shown as the following. Brand personality dimension of Internet shopping malls are 'competence sophistication', 'vitality', 'warmth' and 'reliability' etc. 'Warmth' and 'reliability' have a significant influence on consumer satisfaction and intention to revisit. In particular, 'reliability' showed bigger influence on intention to revisit Internet shopping malls. In addition, consumer satisfaction showed a meaningful influence on intention to revisit. Specific strategy development is needed to strengthen 'warmth' and 'reliability' among brand personality dimensions.

Developing u-Public facilities for application u-City is to combine both the state-of-the art of the construction and ubiquitous computing and must be flexibly comprised of the facilities for the basic service of the building such as air conditioning, heating, lighting and electric equipments to materialize a new format of spatial planning and the public facilities inside or outside. Accordingly, in this paper we suggested the time pattern system for predicting the most basic power system loads for the basic service. To application the tim e pattern we applied SOM algorithm and k-means method and then clustered the data each weekday and each time respectively. The performance evaluation results of suggestion system showed that the forecasting system better the ARIMA model than the exponential smoothing method. It has been assumed that the plan for power supply depending on demand and system operation could be performed efficiently by means of using such power load forecasting.

Aesthetic Movement is an artistic movement which intended to bring up the quality by implanting beauty in everyday life. Aesthetic movement made the beauty itself come alive within each person and thus made it possible to improve the quality of life. Aesthetic Movement emphasized the total artistic concept and this brought new wave to the textile design movement. This paper is the study on the Aesthetisism and the effect that had on the textile design. This study draws the conclusion that there are four areas the textile designs of that era was influcenced by : Firstly , through the influence of the Japanese art, the textile designs came to have 2 dimensional quality. Secondly, through the influence of the pre Raphaelite, colors in the textile designs changed to have pale tones. Thirdly, with the influence of William Morris, the creativity in textile design came to be alive. Forthly, to better the quality of life and design, the cooperative spirits of Arthur Liberty, Morris, Godwin, Lewis Days and other designers, architects including artists contributed a great deal to make the English textile designs to be creative contemproary art works.

In the every genre of arts we can find the oriental Yin-Yang idea which has been descended from olden time in the Orient. It arouses our big interest especially in the domain of design and plastic arts as well as in the every field of human culture, and its study and application will enrich the qualities of design and plastic arts. I think it is with the Yin-Yang idea that we have to chase to our own cultural activities to make differance from the others. Without it, we cannot advance any more the traditional heritage into better and higher state of level than the West, and our philosophy and spiritual activities be stagnant in the same cultural categories as oter countris have in common. The countries which have no distinguishing feature of their own are very easy to place themselves in the border of world culture, not in center of it only to give an immitatin of others. I would like to put great emphasis on Yin-Yang idea in the field of design and plastic arts because it will give newness and novelty to all the p대ple who are not familiar with the oriental Yin-Yang idea.
